Be it known that I, MARTIN ZIEGLER, enginecr, a subject of the King of Prussia, Ge man Emperor, residing at Beuerberg, 'lsartal- 5 balm, in the Kingdom of Bavaria, German Empire, have invented new and useful Improvemcnts in Means for Carrying off Gases from lletorls While being Charged, of which the tollon'i g a spmrilication.

prestnt invention has for its object means for carrying oil the gases rom furnaces or retorts While being clo ged, especially peut-col ing furnaces, so that the Workmen may charge the furnaces without com- I 5 ing in contact with the gases; and it-consists, essentially, of the improvements hereinafter described, and specifically set forth in the appended claims.

'ihe invention is illustrated in the accom- 2o panying drawings, in which 1* igm 5 avcrtical sectional elevation of the de ic i 2 is transverse section on the line A A of Fig. 1..

Similar letters of reference refer to similar 2 5 parts in both views.

Two chargingppenings a, and 0?, situated one beside the other, are indicated in the drawings.

These charging-openings are each provided with a bell-shaped cover 1) b respectiyely, attached to chains 0, running over fixed pulleys (Z. Said covers are guided in suitable guides f, which may be mounted optionally. The covers I) and I) can be raised and lowered by means of chains 0.

A hood II is placed in known manner over the charging-openings. suspended from a girder G or thelilte. Said hood ends above in an outlct-pipe g. A circular casing r r is arranged peinilentnbove 4.0 each charging opening. Said casings or rings may be rigidly connected with said 'hood, and they form protective rings for the personnel serving the furnace. It is essen tial that the gases escape upward through 4 5 said rings Without dispersing at the charging level of the furnace. The covers 0 and may be guided inside the rings r and 1" by means of the guides f, carried by the said rings.

The manner of working the device is substantially as follows: For charging the in nace the pieces of peat are placed round L charging-openings a and c ox-er the liver 1 i: Y

Said hood may be edges of the protective casings r and r, so that each of these rings forms a, tight Wall with the peat sods round said charging-openings. In raising the cover I) or (1 some of the peat sods lying against it fall into the charging-opening, the uses escape through the rings '1" and r'" into the hood ii and escape out oi" the some through the outlet-pipe 9 without opprcssing the workmen. The peat sods which form the protective wall are shovelcd into the furnace uith he covers open. The gases then escaping likewise go through the hood H into the open air; as the outlet pipe 1 exercises a suction etl'cct, like a chimney.

What I claim my invention, and desire to secure by Letters Patent, is-

1. A device for carrying (oil gases when charging verti o1 furnaces or eliorts; portionhtrly peat-coking furnaces'ofi'retorts, with material in lumps or pie 2s, comprising in combination a. hood situated vr ally above the charging-opening of stud ,lurnace or re tort, a cover adapted to close said opening, means adapted to raise and lower said cover, and means surrounding said cover, whereby whensaid cover raised the furnace-gases escape into said hood.

2. A device for Parr mg oti" gases when. charging vertical furnaces, partic larly peatcoking furnaces or retorts, with material in lumps or pieces, comprising in combination a hood situated vertically above the charging-opening of said furnace, a bell-shaped cover adapted to close said opening, means adapted to raise and lower said cover, and means surrounding said cover, whereby when said cover is lowered said material can be pile d against the same and when the same is raised the lurnace or retort escape into said hood.

3. A device for carrying oil gases when charging vertical furnaces, Jarticularly peatcoking furnaces or retorts with material. in lumps or piece-:, comprising in combination a hood situater vertically above the charging-opening of said furnace, a bell-shaped cover adapted to close. said 0pening,'meaus adapted to raise and iowersaid cover, a ring surrounding said cover under said hood, guides in said ring surrounding said cover, whereby when said cover is raised the furee or retort escape through sa d ring .eid hood.

4. Adevice for carrying off gases when charginguvertical furnaces, particularly peatcoking rnaces 0r i'etorts with materlal in lumps or pieces, comprising in combination a hood situated vertically above the charging-openi-ng of said furnace, a bell-shaped cover adapted to close said-opening, means adapted to raise and lower said cover, a ring surrounding said cover under said hood,

guides in said ring surrounding said cover, said ring being arranged pendent at such a distance from said hood that said cover can be raised into the intervening space, whereby when said cover is lowered said material can .be piled against the same and when the same 15 is raisedthe furnace orretort gases escape through said ring into said head, substantially as describe In testimony whereof I have signed my name to this specification in the presence of 20 two subscribing witnesses.
